In □PQRS side PQ∥ side RS. If m∠P = 108degree

natka813 [3]

<h2>Given :-</h2>

In □PQRS side PQ∥ side RS. If m∠P = 108degree

and m∠R = 53degree

m∠Q and m∠S.

<h2>Solution :-</h2>

According to angle sum property

P∠Q=180−∠P

∠Q=180−108

$\boxed{\sf{\angle Q = 72°}}$

For angle S

∠S=180−∠R

∠S=180−53

$\boxed{\sf {\angle S = 127°}}$

In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angl

Bess [88]

Answer:

Angle CAB=56 degrees

Step-by-step explanation:

See the attached image for the diagram.

In triangle BMC

|BM|=|MC| (Radii of a Circle)

Therefore, triangle BMC is an Isosceles Triangle; and

$\angle CBM=\angle BCM=34^\circ$

$\angle CBM+\angle BCM+\angle BMC=180^\circ$ (sum of \angle s$ in a triangle)\\34^\circ+34^\circ+\angle BMC=180^\circ\\\angle BMC=180^\circ-68^\circ=112^\circ$

Next,

$\angle BMC=2\angle CAB $(Angle at center is twice angle at circumference)\\112^\circ=2\angle CAB\\\angle CAB=112^\circ \div 2\\\angle CAB=56^\circ$

Artist 52 [7]

Solve: 4(6x - 10) = 8x + 40

A 0

B.5/2

c. 23

D. 5

<h3><u>Answer:</u></h3>

Option D

The solution to given equation is x = 5

<h3><u>Solution:</u></h3>

Given that we have to solve the given equation

4(6x - 10) = 8x + 40

Let us solve the above expression and find value of "x"

Multiplying 4 with terms inside bracket in L.H.S we get,

24x - 40 = 8x + 40

Move the variables to one side and constant terms to other side

24x - 8x = 40 + 40

Combine the like terms,

16x = 80

$x = \frac{80}{16} = 5$

Thus solution to given equation is x = 5

The circumference of circle A is four times the circumference of circle B. Which statement about the areas of the circles is tru

Brums [2.3K]

Answer:

The area of circle A is 16 times the area of circle B.

Step-by-step explanation:

he area of circle A is three times the area of circle B.

It depends on the value of π.

It depends on the actual diameters of the circles.

The area of circle A is 16 times the area of circle

the circumference of a circle = 2 x pi x r

Let imagine that the radius of B is 2cm

then the circumference of B = 2 x 2 x pi = 4pi

If the circumference of a is 4 times that of B, it means the circumference is 16 and the radius is 8

Area of a circle is pi x r^2

Area of B = pi x 2^2 = 4pi

Area of A = pi x 8^2 = 64pi

64/4 = 16 pi
